Specification of Letters Patent.

Patented Sept. 7,1915.

Application filed March 16, 1910. Serial No. 549,690!

the following to be a full, clear, and exact.

description of the same, such as will enable others skilled in the art to which it pertains to make and use thesame, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to water closets.

It has for itsobject an improved closet bowl, which by its construction is cleanly and sanitary and is especially arranged to be flooded and washed at that part of the bowl where the flooding and washing is most necessary, and in which especial attention has been directed to the production of a bowl that can be made practically.

In the manufacture of earthen bowls (the so-called porcelain bowls that have now come into almost universal use) the number of operations that are required regulate the labor cost of the manufacture. The bowl which has come into universal use is made in pieces which are assembled andplaced together while the clay is yet green, clos ng the joints so that the finished bowl is an 1ntegral structure. In making the bowl in parts in this way the last piece to be placed on the assembled structure is the rim. This is usually made in two parts which are placed independently upon the upper edge of the unfinished bowl, the lower of these two pieces is the one which contains the flushing holes leading through the ring of clay, and this ring, having been put in place and inspected to ascertain that the holes are properly made and properly arranged, is covered by the finishing ring which constitutes the visible rim of the finished bowl, and which in fact constitutes a rim that covers the flushing ring and conceals it entirely; the rim is finished to erase all appearance of scam between the several parts. This rim in the finished bowl is a tube provided along its under side inside the bowl with a number of holes, some of which are round and of small capacity and some of which are oval and of greater capacity; the holes are directed down to direct the flushing water in small streams along the sides and down the front of the bowl. The water is led into this tube at. the rear, sometimes through a double opening directing one-half of the water in one direction and the other half in the other direction, and sometimes through a single opening (as shown in the drawing in this case) which efiects practicallythe same result, causing the water to enter through the opening at the rear and striking the curved surface that is in front of it, and one portion of it passes in one direction and another in the other direction around the hollow of the rim, part of the water escaping downward through the holes in the flushing ring as it travels forward, and part of the water traveling to the extreme front and passing partially around to the rear again, but all eventually drops through the holes in the rim into the bowl. It is quite desirable for.

sanitary purposes that the front of the bowl be elevated somewhat above the middle part, and it is very desirable that there be an abundance of water carried through the hollow rim to the front of the bowl to drop through the holes that are located at or near the front to wash down and clean the front part of the bowl, which is the part of the bowl most liable to be contaminated.

I am aware that there have been many efforts made to raise the front part of the bowl and meet the want which has been referred to above, and all, so far as I have any knowledge of the art, have been open to objections, either as to cost of manufacture or because of the failure to cleanse thoroughly and practically this part of the bowl.

In the drawings which are attached hereto and form part of these specifications, I show the invention which meets the want I have mentioned and overcomes the difficulties; I

show it as applied to two classes of bowls.

Figure 1, shows the invention applied to a bowl in which the front part of the seat is raised above the rear part, and the seat itself is on an incline. Fig. 2, is a longitudinal section of the bowl having a horizontal seat. Fig. 3, is the front elevation of the bowlshown in Fig. 2. Fig. 4, is a plan view of the perforated bottom of the tubular rim. Fig. 5, is a section across the rim.

The seat may be either horizontal or inclined, and in either case is a common, standard, seat that has come into extensive use with different bowls, and this seat may be applied to the bowl shown in either of the forms illustrated.

The main body 1 of the bowl with its discharge outlet 2 maybe of any approved form of construction.

is tubular and is provided with the perforated bottom, that I have spoken of above, and eXtendsentirely around the bowl. This tubular rim curves around the bowl and also curves between the front and rear around an axis that lies across the bowl. Just across the front between the points & and 5, as shown in Fig. 3 the rim is somewhat more flattened, or the radius of curvature is in creased to furnish a better bearing for the front edge of the seat 6. It is not an essential feature of the invention that it be fiattened at this point, but it is essential that from the origin of the curve of inclination to, or near to, the front, there should be a gradual and easy rise which will form no serious obstruction to the How of the water in the hollow of the rim, and yet will raise the extreme front of the bowl to a higher elevation than the rear part of the bowl.

As shown in Fig. 1, the origin of the curve of inclination is near to the rear and may perhaps be said to extend entirely to the rear, although to about the point a the rise is very slight. From this point forward the rise is sharper until it finishes the rise over the curve at the front. This construction forms no serious impediment to the proper action of the water, but directs a large part The water inlet 9 is at the rear of the bowl I and enters the rim 3 just above the floor thereof, and where the floor of the water conduit in the rim is at its lowest point.

What I claim is A water closet bowl having a body portion formed at its upper edge with a flushing rim, the sides of the rim rising in a gradual curve toward the front of the bowl to a. plane slightly above the rear of the bowl, the forward portions of the sides of the rim being connected by a front portion of the rim and formed therewith on broad sweeping lines to merge graduallytogether in both horizontal and vertical projections to afford an unbroken rim having a uniform channel with a continuous smooth wall throughout the rim offering no resistance to the flow of water therethrough, the forward connecting portion of the rim forming a seat rest, the relation of the front and rear portions of the bowl being such as to support a seat of the usual formation in an approximately horizontal plane, in combination with said approximately horizontally disposed seat hinged to the rear portion of the bowl and resting on the front thereof.

In testimony whereof, I sign this specification in the presence of two witnesses.
